He looks a little concerning because his third eyelid is showing, but I woke him up out of a sound sleep, so he was a little groggy.

Kittens are born with their eyes closed, and it takes about a week for them to open. Once they do they don't have very good control over their focus and direction, so most of what they see is fuzzy and out of focus. Like learning to walk, and learning to control their claws, learning to focus on things is something they have to learn. If you look at all the other photos, you'll see he wasn't the only one.
